rrude oil or other liqu d fuel, nith a mini mum amount of soot.

As a more sporili object, the pre it invention aims to provide an oil st ve llitjlllllw ingado-vndraft air tube, in courier-lion with combustion supporting means at the lower end of the tube, and n fians for supplying the liquid fuel to the aid means, whereby the billowing air will dirt-vi, the flames radially in all directions from the lower end of the down draft tube.

it also within the spirit of the present inwntion, to provide an oil stove of (our: paratively simple, light, and durable as well as inexpensive constitution. \thi-ih shall be simple, pra ifl'tll and t-l hiont in operation.

(All he (:Ullt 'iv ithln tilt r /Ugn", Hi What is Lied, without 4 epuriing from ulu-spirit of the invontioi'i.

The invention has: been illustrated in its preferred emlmdhne-nt in the accompanying (,llrml'lllg', wherein the figure is a central vertical section f the. improved, oil store.

In carrying out, the present inwntion, there is provided an upright oyliialrical rasing 1, which may be of sheet nretat and which l a top or cover attacned to its iq'iper end, a st ve pipe 3 being connected to tho, to or rover :3 to carry off the products di? the rasing i. The front provided with doorand, l a 3 atom :hed to the lower m an; o tion mic-ma being nude I l l l l l l i l l l l l l t l legs 6 being preferably, although not necessarily, of cast metal.

The bottom 5, which forms an essential feature of the present invention, has its new tral portion raised, or conical in form, as at '7, and has an annular depression 6 formed adjoining its margin or periphery, or hotween the raised or conical portion T and the rim or periphery of the bottom. Upon the apical portion of the bottom, is disposed at cirmilar or disk-like pad or wick it of a hestos or similar material having absorbent properties; .A n angular down draft tube 10 is dirqpiosed within the casing 1 and has one arm or end attached to the back of the easing t o communicate therethrough. while the other or free arm of the tube 10 depends and terminates adjoining, but slightly spaced from, the pad or wick 9.

The fuel tank It is supported from the bark of the stove casing l, by n rans of a pair of arms 12' secured to the bark of the casing: above the inlet end of the down draft air tube 10, and formed with bands 13 at their free ends embracing the tank 11. A liquid fuel pipe 14 is attached to the bottom or lower end of the tank 11 and extends axially through the upper or horizontal a rm of the down draft tube 10, the free end or nozzle 13 of the pipe 14 being bent angularly downward within the depending or vertical arm of the tube 10. The pipe 14 is provided with a needle or other valve 16 for controlling the passage of fuel therethrough from the tank ll. A second liquid fuel pipe 17 is connected to the bottom or lower end of the fuel tank 11, and extends below the stove casing l, the free end or nozzle 18 of the pipe 17 being engaged upwa: dly through the apex of the bottom 5 and throrgh the wick 9. The pipe 17 is provided with a needle valve '19 for controlling the flow of fuel therethrough. A ballle plate is bolted or otherwise secured to the legs; 6 between their lower ends and the bottom 5 of the stove casing, to direct the downwardly radiated heat toward the several sides, and to prevent the downwardly radiated heatfrom reachin g or attacking the floor.

in operation, either of the liquid fuel supply pipes l t or 17 may be opened, to supply the fuel to the wick 9 drop ,y drop. soon as sullicient fuel is absorbed by the wick t the wick may be lighted, by opening the door l, which will start the combustion, the air flowing doivnwardly through the down draft tube 10 and in escaping from the lower end of the down draft tube, Will direct the flames radially, the flames then rising along the walls of the casing 1. In this manner, a uniform heat is established around the stove, and the heat will also be radiated downwardly from the bottom of the stove, which is highly desirable. The air being drawn into the down draft tube 10, will create a current of air around the fuel tank 11, whereby the said fuel tank will be cooled. or prevented from heating. The wick 9 being carried by the apex of the bottom, and the bottom being )rovided with the annular depression 8, wiil permit the flames to properly issue radially from the wick 5 without burning the bottom, it being observed that the heat will be radiated down wardly through the bottom of the stove easing. Particular attention is directed to the fact that the lower end of the down draft tube tern-iinates adjacent the apex of the raised portion of the bottom, there being only a slight space between the wick and the down draft tube, whereby the air passing from the lower end of the down draft tube, will contact with and tend to penetrate the wick, to assist in the vaporization of the fuel in an elleetive manner. The battle plate J0 prevents the downwardly radiated heat from reaching the floor, that is, directly from the bottom of the stove casing, but directs the said heat laterally. The battle plate 20 also serves to steady the legs 6, and may serve as i a. foot rest, whereby the feet may be readily warmed by the downwardly radiated heat.

The present stove or burner will produce a maximum heating effect, with a minimum amount of fuel, and with a minin'nuu amount of soot.

After the combustion has been started. it will be manifest that the fuel will be readily vaporized as it reaches the wick 5). The air portion, and a liquid fuel supply pipe passed 5-- upwardly through the apex of the said raised portion.

:2. in an oil stove, a casing, the bottom of which has a central raised portion and a surrtnnnling annular depression, a. down 6 draft tube within the casing terminating adjacent the apex of the said raised portion, a wick disposed upon the apex of the said raised portion, and means for supplying liquid fuel to the said wick, there being a 6 slight space between the wick and draft tube.

3. In an oil stove, a casing, an angular down draft tube having one arm attached to one wall of the casing and having it: 7 other arm depending in the casing, combustion supporting means disposed below the. lower end of the said tube, a liquid fuel tank supported from the said wall of the casing adjoining the inlet end of the said 7 tube, and means for conducting the fuel from the tank to the said combustion supporting means.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
